I ran into problem when creating Case object with customer field values. When ever I created a Case and setting the customer field Address__c (i.e String type) I got the Error as:
Error: Unable to create/update fields: Address__c. Please check the security settings of this field and verify that it is read/write for your profile.
The same thing happen with my other customer field value Property_No__c
What did I do wrong? Why can't these field values be set? What the restriction(s) on Case fields ?
